What is the range if times that the middle 50% of sophomores spend on homework per night?

Step-by-step explanation:

Another way of stating this problem is find the Interquartile Range which is

Quartile 3 - Quartile 1.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
